Ji-Chang He, PhD

Research Associate Professor of Optometry

Dr. He has been a faculty member at the College for the past five years. In this capacity, he conducts independent research and works collaboratively with faculty on current research initiatives. His primary area of interest is the optics of the eye and he is currently investigating wavefront aberrations of the human eye, specifically focusing on their characteristics and sources. Dr. He is using various techniques including the wavefront aerometer, corneal topography system, and Scheimpflug imaging system to measure ocular aberrations of the entire eye and aberrations on the surfaces of the cornea and lens.

A thorough knowledge of wavefront aberrations enhances the overall understanding of the optics of the eye and aids practitioners in an accurate correction of aberration-related vision problems. Dr. He hopes that his research will provide ophthalmologists and optometrists both with comprehensive and effective information for wavefront guided vision corrections such as refractive surgery, cataract surgery, and contact lenses. In past years, Dr. He has presented the findings from his studies to the Association for Research in Vision and Ophthalmology at its annual conferences.

Dr. He earned a PhD from the Department of Psychology at the University of Chicago and has a master’s of science degree in physiological optics from the Shanghai Institute of Physiology Chinese Academy of Science. He is a member of both ARVO and the Optical Society of America. He is also on the editorial review board for the Journal of Optometry.
